Poor diets are the leading cause of death and disability in the United States, yet nutrition remains largely missing from our healthcare system. This critical gap costs our economy $1.1 trillion annually in healthcare spending and lost productivity from suboptimal diets and food insecurity—equivalent to the entire economic output of the food system. Food is Medicine (FIM) interventions represent a paradigm shift that integrates evidence-based nutritional support directly into healthcare delivery through programs like Medically Tailored Meals, Produce Prescriptions, and targeted grocery interventions. National implementation could prevent 1.6 million hospitalizations and save $13.6 billion in healthcare costs in the first year alone, while addressing health inequities by targeting social determinants that disproportionately affect lower-income and marginalized communities. The evidence is clear: integrating nutrition into healthcare delivery isn't just beneficial—it's essential for creating a sustainable, effective healthcare system that promotes health rather than merely treating disease.
